[0020] When in use, the outer shell 1 can be carried and moved by the handle 5. When the outer shell 1 is moved, the protective plate 3 can protect the purification body 2 to prevent it from being contaminated and damaged. After the outer shell 1 is placed at the designated position, the protective plate 3 can be pulled up to leak out the purification body 2. After connecting the tube body, the device can be turned on to purify the blood. After pulling open the protective plate 3, the adsorption chamber 7 can adsorb the supporting surface of the outer shell 1 to enable it to maintain good stability and prevent the outer shell 1 from tipping over or shaking. Subsequently, blood and the like can be temporarily stored in the liquid storage chamber 22, and the liquid storage chamber 22 can be heated and insulated in conjunction with the water bath heating chamber 18 to provide a good storage environment for it.

[0021] Embodiment 2: Based on Embodiment 1, a sealing gasket 6 is fixed at the bottom of the outer shell 1 to seal the fit between the adsorption chamber 7 and the supporting surface of the outer shell 1. The adsorption control mechanism includes a movable plug 8, a control rod 9, a drive plate 10 and a connecting groove 11. The movable plug 8 is arranged inside the adsorption chamber 7 and between the adsorption chamber 7 to form an up-and-down sliding structure.

[0022] When controlling the movement of the protective plate 3, the protective plate 3 can be pulled upward by the auxiliary handle 4 to release the attraction of the attraction block 13 to the magnetic block 12, so that the protective plate 3 moves upward to purify the leakage of the body 2. When the protective plate 3 moves upward, the driving plate 10 slides in the connecting groove 11. When the driving plate 10 moves to the lower end of the connecting groove 11, the protective plate 3 continues to move upward. The connecting groove 11 will pull the driving plate 10 upward, so that the driving plate 10 drives the movable plug 8 to move through the control rod 9. The movable plug 8 moves upward to generate negative pressure in the adsorption chamber 7, and the adsorption chamber 7 is adsorbed on the support surface to position the outer shell 1. At the same time, The locking groove 14 moves to the locking block 15, and the locking block 15 is connected to the locking groove 14 under the action of the reset spring 16, limiting the protective plate 3 to keep it in the open state. When the protective plate 3 needs to be lowered later, the control head 17 can be pushed to drive the locking block 15 to move, and the connection between the locking block 15 and the locking groove 14 is released. The protective plate 3 can move downward to reset, and the attraction block 13 and the magnetic block 12 attract each other to position the protective plate 3. After the protective plate 3 moves downward, the connecting groove 11 squeezes the driving plate 10 downward to control the movable plug 8 to reset, thereby releasing the adsorption effect of the adsorption chamber 7.
